Association of persistent hyperglycemia with outcome of severe traumatic brain injury in pediatric population

Purpose

Hyperglycemia is a common secondary insult associated with an increased risk of mortality and poor outcome in traumatic brain injury (TBI), but the effect of hyperglycemia on outcomes of severe TBI in children and adolescents is less apparent. The aim of this study was to evaluate the association of hyperglycemia with mortality in pediatric patients with severe TBI.

Methods

In this cross-sectional study, data of all children and adolescents with severe TBI admitted to Poursina Hospital in Rasht, including age, gender, Glasgow Coma Scale (GCS) upon admission, mortality rate, hospital length of stay, and serial blood glucose during the first three consecutive ICU days following admission, were reviewed from April 2007 to May 2011. After univariate analysis and adjustment for related covariates, logistic regression model was established to determine the association between persistent hyperglycemia and outcome.

Results

One-hundred and twenty-two children were included with a median admission GCS of 6 (interquartile range (IQR) 5–7) and a median age of 13?years (IQR 7.75–17). Among them, 91 were boys (74.6?%) and 31 were girls (26.6?%); the overall mortality was 40.2?% (n?=?49). Patients who died had a significantly greater blood glucose levels than survivors for the first 3?days of admission (P?=?0.003, P?P?=?0.001, respectively). Moreover, persistent hyperglycemia during the first 3?days of admission had an adjusted odds ratio of 11.11 for mortality (P?Conclusion Early hyperglycemia is associated with poor outcome, and persistent hyperglycemia is a powerful and independent predictor of mortality in children and adolescents with severe TBI.     

Importance of Mean Platelet Volume in Predicting Cardiac Mechanics Parameters and Carotid‐Intima Media Thickness in Children With End‐Stage Renal Disease and Comparison With Healthy Children

Cardiovascular disease (CVD) is the major cause of death in children with ESRD. Echocardiography and Doppler ultrasound are useful devices for diagnosing cardiovascular abnormalities in such patients. However, they are expensive, difficult to perform as a routine, and not available in many centers. Therefore, finding a more accessible and inexpensive method for CVD evaluation biomarkers is needed. The aim of this study was to evaluate the relationship between mean platelet volume (MPV) as a routine hematological parameter with cardiac mechanics characteristics in children with ESRD. Forty‐two children under dialysis and 60 age‐ and sex‐matched healthy subjects as control group were enrolled in the study. Carotid‐intima media thickness (CIMT) and echocardiographic parameters were measured in both groups. In addition, hematological and biochemical variables were evaluated in blood samples of participants. MPV was significantly higher in patients than in controls. CIMT, left ventricular mass index (LVMI), end diastolic diameter, strain rate, and global longitudinal strain were significantly different between the two groups. MPV was positively correlated with LVMI and inversely with ejection fraction. In receiver operating characteristic (ROC) curve analysis, the area under the ROC curve (AUC) values for MPV in predicting left ventricular hypertrophy (LVH) and abnormal CIMT were 0.65 (P = 0.07) and 0.53 (P = 0.74), respectively. MPV was correlated with some cardiac abnormalities in children with ESRD. However, it could not show appropriate predictive values in diagnosing LVH and subclinical atherosclerosis. Further studies with prospective design could shed more light in this topic.     

The effect of short message service (SMS) on knowledge and preventive behaviors of diabetic foot ulcer in patients with diabetes type 2

ObjectiveThe present study aimed at evaluating the effectiveness of an educational intervention via mobile cells on foot care knowledge and foot care practices in patients with type 2 diabetes.Material and methodsThis is an interventional quasi-experimental study carried out in 4 community health centers in Andimeshk City in Iran in 2017. Of 160 patients 80 cases were randomly assigned as intervention group and 80 patients as the control one. A three-section questionnaire completed by a face-to-face interviewing used for data collection before and after the intervention and three months after the education. Fasting Blood Sugar (FBS) and Hemoglobin A1C (HbA1c) tests were done for both groups in a single laboratory before and three months after training.ResultsThe mean age of patients in intervention group was 48.11 ± 9.7 and control group was 47.3 ± 7.9 years. The awareness of the patients related to diabetes foot care, in the intervention group after the training significantly improved (P < 0.001). The mean scores of preventive behaviors of diabetic foot significantly increased in the intervention group (P < 0.001).ConclusionThe findings indicate that educational intervention based on short message service (SMS), resulting in improve foot care knowledge, foot care practices and metabolic control in patients with diabetes type 2.     

Identification of disease-causing variants in the EXOSC gene family underlying autosomal recessive intellectual disability in Iranian families

Neurodevelopmental delay and intellectual disability (ID) can arise from numerous genetic defects. To date, variants in the EXOSC gene family have been associated with such disorders. Using next-generation sequencing (NGS), known and novel variants in this gene family causing autosomal recessive ID (ARID) have been identified in five Iranian families. By collecting clinical information on these families and comparing their phenotypes with previously reported patients, we further describe the clinical variability of ARID resulting from alterations in the EXOSC gene family, and emphasize the role of RNA processing dysregulation in ARID.     

Left ventricular intra-myocardial dissection after myocardial infarction

Left ventricular (LV) intra-myocardial dissection or dissecting hematoma is a rare complication of myocardial infarction that could occur in the acute phase, during remodeling process and even after coronary revascularization. LV intra-myocardial dissection has a high mortality, and the best management strategy remains controversial. Here, we present a case of dissection of left ventricle late after anterior myocardial infarction diagnosed by multimodality imaging.     

Resuming Breast Imaging Services in the Aftermath of the COVID-19 Pandemic: Safety and Beyond

As the Coronavirus disease 2019 (COVID-19) epidemic begins to stabilize, different medical imaging facilities not directly involved in the COVID-19 epidemic face the dilemma of how to return to regular operation. We hereby discuss various fields of concern in resuming breast imaging services. We examine the concerns for resuming functions of breast imaging services in 2 broad categories, including safety aspects of operating a breast clinic and addressing potential modifications needed in managing common clinical scenarios in the COVID-19 aftermath. Using a stepwise approach in harmony with the relative states of the epidemic, health care system capacity, and the current state of performing breast surgeries (and in compliance with the recommended surgical guidelines) can ensure avoiding pointless procedures and ensure a smooth transition to a fully operational breast imaging facility.

Three-year efficacy and patency follow-up of decellularized human internal mammary artery as a novel vascular graft in animal models

Background

Various investigations have reported that the internal mammary artery (IMA) is an efficient and functional choice of conduit for vascular graft surgeries, especially for coronary artery bypass grafts; however, the quest to find an ideal vascular substitute remains. We hypothesized that acellular IMA could be an appropriate graft for small-diameter vascular bypasses that could be used in various surgeries including coronary artery bypass grafting.
